Sound Transit Regional Transit Long-Range Plan
Draft Supplemental Environmental Impact Statement
December 2004

Dear Mr. Kennedy:

This Draft SEIS is supplemental to the Regional Transit System Plan, Final
Environmental Impact Statement, March 1993. My comments on that earlier EIS [1]
primarily concerned congestion pricing and the capacity of bus vs rail systems. In the ten
plus years since that EIS several significant developments have occurred. The first is that
pricing has come into its own, with several projects, both domestic and foreign having
been built, and many more in planning [2]. The second is that what is now called Bus
Rapid Transit (BRT), systems of which have been in place in South America for decades,
has belatedly been recognized for having capacity similar to heavy-rail. [3] The third is
that “inside out” commuting has developed in this region to such a level that it is equal to
traditional, “outside in” commuting.

My remarks here are primarily addressed to the confluence of these developments, a
confluence not recognized in the DSEIS. Specifically, to meet the reality of these
developments, a plan for running BRT on High Occupancy / Toll (HOT) lanes should be
developed as a formal third alternative within the Final SEIS. If it is, I believe a fair
appraisal [4] will show that such a BRT/HOT Alternative has far more people-moving
potential than light rail (LRT), can be built at a fraction of its cost, and better serves the
evolving transportation needs of the region. As it stands the DSEIS is essentially a
advocacy for extension of the Link light rail system, with the alternatives, such as they
are, being little more than “straw men.”

Transportation systems are inherently tied into land use patterns. And any document
such as the DSEIS, while naturally replete with facts and figures, almost of necessity
expresses a philosophy or world view connecting the two. In this case, the embedded
philosophy is one with which I am in substantial agreement, namely Transit Oriented
Development (walkable, mixed-use neighborhoods and activity centers connected by
quality, high capacity transit). [5]

Advantages of the BRT/HOT Alternative

The question is, is light rail the best technology for making connections between these
neighborhoods and activity centers? While that is currently the “conventional wisdom”
among transportation aficionados in this region, the newer BRT/HOT Alternative has
some major advantages [6]:

1) It is cheaper per mile, and thus the whole 125 mile HCT network can easily be built
   within the identified 25 year time frame. With the LRT system, due to budget
   constraints, only a small portion of the network could be built within this period. [7]
2) In its turn this means that far more neighborhoods, communities, and activity centers
   can be connected by HCT, better meeting the goal of creating Transit Oriented
   Development (TOD).
3) It has far more capacity than the LRT system, particularly with the limitations imposed
   by the confluence of a) at-grade travel in the Rainier Valley, b) the merge of an at-
   grade (south) and grade-separated (east) line, and c) the relatively short stations in
   downtown Seattle.
4) It better serves the region’s evolving “inside-out” commuting pattern.
5) It is faster than the light rail system, particularly where LRT is at-grade.

1. Cheaper per mile. The DSEIS envisions LRT connecting Everett, Seattle, Tacoma,
Bellevue and beyond. But because it doesn’t attach a price tag to this vision, this is more
a wish list than an objective. If cost no object, then why not heavy rail as envisioned in
the 1993 EIS, indeed why not maglev? The price tag for the downtown Seattle to
Northgate section, which is assumed under all alternatives in the DSEIS hasn’t even been
arrived at yet. None the less we can make what is admittedly a guess, albeit an informed
one: $30 - $40 Billion for the full system. [8] The corresponding figure for a HOT lane
network is approximately $2 billion. [9]

This latter figure doesn’t include things such as converting the reversible lanes on I-5 to
HOT lanes (a WSDOT rather than a Sound Transit responsibility) or building a new bus
tunnel in downtown Seattle (on which more later). But it would be sufficient to provide
the entire metropolitan Puget Sound region with a BRT system, most of it running at
highway speeds (50 - 60 mph) even during the height of rush hours. Of course these are
“back of the envelope” figures, but note that the full BRT system is grade-separated
while important links in the LRT counterpoint (eg along Martin Luther King Jr. Way) are
at-grade. Despite this qualitative difference in favor of BRT, for a similar-length system
LRT is fifteen times (15 x) more expensive than BRT. That order-of magnitude
differential leaves a lot of room for back-of-the-envelope error, and strongly suggests that
a third, BRT/HOT Alternative should be fully vetted in the Final SEIS.

2. Better meets the goals of Transit Oriented Development. The DSEIS says that the Plan
Alternative would “result in less dependence on automobile travel and greater transit- and
pedestrian-friendly development activity.” (4.10-10) This is tantamount to saying that it
would cause Transit Oriented Development. The No Action Alternative, on the other
hand, allegedly could result in “increased pressure for suburban sprawl” and “pressure to
build highway improvements.” (4.10-14) However, for tens of billions of dollars the
Plan would have only the modest effects on automobile traffic. [10] And the more likely
outcome is that because of its gargantuan expense and extraordinarily modest results, the
pressure for auto-mobility, with associated “sprawl” would continue unabated. [11]
Thus the Plan Alternative could achieve the exact opposite of the result projected in the
DSEIS. And while it’s not clear that any transit system can reduce automobile travel, if
the goal is to connect walkable communities [12] with swift, quality transit, then the
BRT/HOT Alternative is superior, simply due to the fact that it can easily be built within
the 25 year DEIS time-frame [13], while the Plan Alternative is more likely a hundred-
year project.

3. More capacity. That buses with off-line loading have far more capacity than rail was
one of the two main points I made in my comments on the 1992 DEIS [14], and the past
decade has just made this point stronger. The maximum seated [15] throughput for the
Link LRT system north of downtown Seattle, according the DSEIS is 7,400 seats per
hour per direction. [16] The line capacity of a bus lane with off-line loading [17] (or of a
HOT lane that has become a bus lane due to extraordinary transit demand) is
approximately 44,000 seats per hour per direction, about six times the LRT figure. [18]

This is not to say that downtown Seattle, to take the most salient example, can handle
this level of bus through-put absent major upgrades to transit facilities. It cannot. But
then, according the DSEIS it doesn’t need to. What it needs to accommodate is, at most,
7,400 seats per hour. And this buses can do rather easily. [19] I will develop this
conclusion under my consideration of the I-90 HCT alternatives.

4. Inside-out commuting. Commuting in the region is currently as much “inside-out”
(Seattle to the Eastside) as it is “outside-in.” A claimed benefit of the Plan Alternative is
that it will handle, traditional, outside-in commutes better because rail passengers to
downtown Seattle business district wouldn’t have to transfer on the destination side of
their trip (although, due to inherent limitations of rail, they would normally have to
transfer on the origination side). As for inside-out commuting, however, since the
Eastside has less concentrated employment centers, rubber-tired transit (buses, vanpools,
carpools) are inherently more convenient than rail, since the latter will almost always
require a destination-side transfer -- and in most cases require a origination-side transfer
as well.
5. Faster. Because they always give absolute priority to transit, and because they are
priced to keep traffic moving at highway speeds, HOT lanes move BRT buses at 50 to 60
mph 24/7. LRT moves at various speeds, estimated in the DSEIS to be an average of 25
to 30 mph. [20]

Obviously the above represents only the most cursory examination of a comparison of the
BRT/HOT vs the LRT Alternatives. The Final SEIS should examine these honestly [21]
and in depth.

I now very briefly examine the application of the BRT/HOT Alternative as it relates to a
couple of specific corridors referenced in the DSEIS.

BRT/HOT on I-405

The “I-405 Congestion Relief and BRT Project” report calls for BRT on HOV or future
HOT lanes (Appendix O of the DSEIS, p 19). Given the above discussion, as well as the
fact that there is plenty of room within this corridor for off-line bus stops, BRT/HOT is
the obvious HCT choice for this corridor. [22] The only significant issue is HOV to HOV
(which would become HOT to HOT) interchanges on I-405. But regardless of the HCT
option chosen, these interchanges need to be built in any event. And since they are the
responsibility of WSDOT (and thus are exterior to Sound Transit’s budget), this is really
a non-issue. Sound Transit does have the responsibility to build the BRT stations and the
direct-access ramps, but these are relatively minor items compared to constructing a
whole new right of way for trains (or, for that matter, for buses)

BRT/HOT on I-90

The I-90 HCT corridor is a strong, if largely implicit focus of the DSEIS. The DSEIS
contains a BRT option for this corridor, which is sketched out in Appendix N, having the
following elements:
    1. The I-90 center span becomes a busway.
    2. At least three freeway BRT stops are on-line (in the parlance of the document,
    3. The central portion of the north-south BRT line is over a Burlington Northern
       railroad right of way (ROW).
    4. Buses run in mixed-traffic city streets in downtown Seattle.

There are major problems with all these elements:

1. The I-90 center span becomes a busway. Converting the I-90 center span to a busway
certainly creates huge transit capacity. [23] In fact the capacity is such that to equal the
seated capacity of rail on the bridge there need to be only one bus traveling each direction
on the bridge at a time. [24] Needless to say, if this were the only traffic on the center
span of the bridge, that would be a huge waste of the capacity

Also, because the center span under this configuration would appear nearly empty (one
bus traveling each direction at a time), this is probably not “politically sustainable,” since
commuters would be irate to see a nearly empty center span. However, with the center-
span converted to HOT instead of bus-only lanes, center-span capacity would not to be
wasted. To the extent that buses and vanpools didn’t use the available capacity, it would
be made available to non-transit users, taking some pressure off the general-purpose

2. At least three on-line freeway BRT stops in the I-90/I-405 corridors are envisioned in
the DSEIS. On-line stops hugely reduce the potential through-put of a BRT system.
With such stops express buses have to operate in the same manner as trains: when a train
is stopped in a station another train can’t pass it, and therefore sufficient “headways”
must be built in to the system to avoid collisions. The result is that the capacity of rail
systems are determined by the headways necessary to avoid collisions at stations. Such
headways are typically no less than every few minutes. However, with off-line stops
buses on HOT lanes can operate every few seconds. [25] I made this point in my
comments on the 1992 DEIS [26]

3. The central portion of the north-south BRT line is over a Burlington Northern ROW.
First, as mentioned above, if the HOV lanes on I-405 are converted to HOT lanes, they
will have enormous transit capacity, and therefore the use of the BN ROW is
unnecessary. Second, a railway ROW is not a good fit for a busway: it is too narrow,
and of course the railroad trestles would have to be completely rebuilt. Ironically this
ROW is one place in the region that may be a relatively good fit for light rail or DMU
(diesel multiple units). After all, as in San Diego or Saint Louis, the tracks are already in
place. [27]

4. Buses run in mixed-traffic city streets in downtown Seattle. The DSEIS contemplates
the completion of the Sound Move program, which includes the annexation of the DSTT
by trains, with buses being “turned out on the street.” While such annexation is, in my
opinion, misguided, [28] I will not discuss it further here. But even with this annexation,
are there alternatives to buses fighting their way through downtown Seattle traffic? The
answer, of course, is yes.

First, third Avenue could remain a bus-mall, either full-time or rush hours only, as it will
be during conversion of the DSTT to rail use
Second, the region has made the decision to tear down the Alaska Way Viaduct and
replace it with a tunnel. If this is carried forward, Alaska Way will gain substantial,
above-ground capacity, which could be used by buses.
Third, the cost of LRT in the I-90/Eastside corridor is enormous [29], and in order to
make a valid comparison of alternatives, reasonably equal funds must be assumed for
each. Otherwise one side is, metaphorically speaking, fighting with a spear, a dagger, a
net, and a trident, while the other is unarmed: not exactly a fair fight. For a fraction of
the funds dedicated to the Eastside/I-90 LRT alternative, Sound Transit could build a
second transit tunnel in downtown Seattle, this one optimized for buses. [30]

Eventual Further Development of BRT/HOT Alternative

The BRT/HOT Alternative sketched out there is hardly the be all and end all. Further
development of the principles embodied in this alternative could lead to congestion
pricing of all freeway lanes as I advocated in my 1992 comments to the former EIS. [31]
General Congestion Pricing, coupled with demand-responsive transit and instant
carpooling, is the ultimate – albeit optional -- development of the principles underlying
this third, BRT/HOT Alternative. [32]


However, I am not advocating general Congestion Pricing here. Rather I am advocating
that Bus Rapid Transit running on a system of HOT lanes be fully and fairly developed as
a formal, third Alternative in the Final Supplemental EIS. Anything less constitutes a
breach of duty to fairly consider all reasonable alternatives, as well as a willful ignore-
ance of the situation facing our region.

Thank you for consideration of these remarks.

BRT projects
In-place projects include:
- SR 91 “Value” lanes in Orange County, California
- I-15 HOT lanes in San Diego, California
- Katy Freeway HOT Lanes in Houston, Texas
- London, England, cordon pricing
- Singapore, cordon pricing
Many pricing projects are in planning, including the Washington State SR167 HOT lane Pilot

BRT through-put similar to heavy rail
According to FTA documentation the San Paulo and Bogotá BRT systems carry 30,000 + people
per hour per direction (see Appendix D). This is comparable to most heavy rail systems
(Appendix E), and is well above the through-put for any light rail line. The 1993 Regional
Transit Project EIS estimated the capacity of its “rapid” (ie “heavy”) rail Preferred Alternative at
22,400 people per hour per direction.

Note that the preferred alternative in the 1993 EIS was a totally grade-separated system, similar to
BART or the DC Metro. That document examined and rejected at least two iterations of non-
grade-separated “light” rail such as Sound Transit is now constructing along Martin Luther King
Way and rejected those alternatives. See also the first paragraph of footnote 2, Appendix B.

fair appraisal
There can be no doubt that Sound Transit and its predecessor agencies have frequently been
guilty of “stacking the deck” in favor of whatever rail alternative was currently in favor, indeed
the deck is clearly stacked in the current DSEIS. To take a couple representative examples:
         In order to justify the Sounder commuter rail line to Everett ST needed to show a time
savings compared to competing bus service. It managed to do this by comparing the then-
prospective rail line, not to then-existing express buses running between Everett and downtown
Seattle but rather to a “milk run” that stopped every few blocks and required a transfer to boot.
         When politics required a diversion of the preferred grade-separated rail system running
down the Duwamish to a system running through the Rainier Valley (currently under
construction, and contrary to the findings of the 1993 EIS, being built at-grade) this was
accomplished by covertly undermining the Duwamish route (see footnote 2 in Appendix B).
In these and numerous other instances Sound Transit has acted in abject and flagrant bad faith.
TOD vs “sprawl”
The dominant form of development in post WWII America is characterized by
- Separation of work, shopping and housing
- Near-exclusive dependence on the automobile
- Abundant free parking.
- Spread-out development to accommodate the automobile.
- Dominance of the automobile over the pedestrian
Together these are generally characterized by the term “sprawl.”
Transit Oriented Development (TOD) is simply a return to an earlier built-space form, one
characterized by
- Mixing of work, shopping and housing in a single district or neighborhood
- Ability to move about conveniently via transit
- Parking that is subordinated to the “walkability” of a neighborhood
         (although it may – or may not still be “abundant”)
- More compact development along with characteristics, such as small blocks,
         that increase “walkability.”
- Dominance of the pedestrian over the automobile

major advantages
The advantage of the LRT system is that it has, at least in the eyes of its proponents more
“cachet,” often being described as being “world class,” and thus might better address whatever
civic insecurities the region labors under. A remark that has stayed with me was made at a
Camber of Commerce conference in Vancouver BC by a Portland attorney, who said that that
latter city’s light rail system had “make it ok” to use transit again. This is non quantifiable, but
may be a real phenomenon. On the other hand, studies have conclusively shown that people are
not so much concerned about what kind of wheels their “transit box” runs on as they are about
convenience, safety, headways, and door to door travel time. Some Paris subway use rubber tires.
There is no indication that if they left their tracks for the last mile or so of the journey to deliver
people to their precise destination that people would see this as anything but a plus.

budget constraints
As I understand it the increase of costs of the Link light rail system vis a vis the Sound Move
document is currently at 170%, ie it is 2.7 times the cost indicated in that document. At the time,
figures in Sound Move were represented to the public as being “consciously conservative.”

the full network
see Appendix F
and approximately $6 Billion (2.4 + 3.6) for SeaTac to Northgate

cost of a HOT network
The cost to complete the “core” HOV lane network is, according to WSDOT, approximately
$1,650 million. Other costs are $290 million for associated HOV to HOV ramps, and $60 million
for a bus-only Ravenna to Stewart south-bound lane on the I-5 express lanes. There is no public
cost to convert HOV to HOT lanes, as that is born by paying, non-transit users. (See also
Appendix B)
modest effects on traffic congestion.
According to Jim MacIsaac (12/9/04) (Appendix F) $28 Billion in rail capital costs and a
probably additional $10 Billion in O&M (Operations and Maintenance) costs by Sound Transit
through 2030 would serve to offset ONE years growth in traffic.

pressure for auto-mobility would continue
According to John Tierney of the New York Times, “highway congestion increased in Portland
more than any other American city in the 15 years after the first light-rail line opened.”
( Therefore the argument that rail decreases the
rate of growth of automobile travel is at best unsubstantiated, and more likely is simply false.

Another important point that Mr. Tierney makes in this article is that pricing keeps the “traffic
pipes” at their maximum dimension at all times. Normally during rush hours these “pipes”
reduce flow to a trickle. Therefore, pricing is a powerful form of capacity enhancement – sort of
freeway-onramp metering on steroids.

reduce congestion
See previous footnote in reference to Portland’s failure to reduce congestion.
Connect walkable communities
Note that there are various cities that have Transit Oriented Development with no trains, and
others with trains but no TOD. Therefore rail is neither necessary nor sufficient for TOD.

easily built in the next 25 years
The cost of a 125 mile basic HOT and bus-only lane system is approximately $2 Billion (see
footnote 9), ie less than the cost of Initial Segment of Link from Westlake to north of SeaTac
Airport. (Note that Initial Segment is the starter system of Phase I of the Link system, which
itself was characterized as a starter system within Sound Move. So Initial Segment is a starter
system of a starter system.)

my comments on the 1992-3 EIS
See Appendix A

why seated
It is essential that comparisons be made on an “apples to apples basis.” Seated capacity in each
case is the easiest comparison to make, which is why I use it. It is also possible to compare
seated plus standing capacity in each case. Note that in comparing light rail to buses in the
DSTT, however, Sound Transit has been guilty of comparing a percentage of bus seats against a
multiple of rail seats. (see footnote 6 to Appendix B)

7400 seats per hour
60 minutes per hour / one train every 2.4 minutes (page 4.9-26) = 25 trains per hour
25 trains per hour x 4 cars per train x 74 seats per car = 7400 seats per hour
off-line loading
As is the case with rail, buses with on-line unloading/loading must maintain sufficient headways
to prevent a bus stopped at a station from being run into by another bus coming up behind. On-
line loading for what we now call Bus Rapid Transit seems to have been a premise of the 1993
EIS (see Appendix C, top illustration of a “Transitway”). This premise also appears to have
carried over to the current DSEIS, as Appendix N to that document envisions “in-line” loading
for BRT several places in the I-90 / I-405 corridors.

According to Sound Transit, light rail could run on as 2.4 minute headways (see footnote 16)
north of downtown Seattle. With on-line loading it is likely that a similar (or somewhat better)
time between buses could be maintained. However with off-line loading the time between buses
is reduced from minutes to seconds, and capacity is commensurately increased:

     “Capacity of a route or of a group of routes on the same facility is almost always determined
     by conditions at stops areas rather than line conditions. ... When stops are made off the main
     line or artery, capacity is determined by the safe separation between transit units. Thus, on
     exclusive busways or bus lanes on freeways, with off-line bus stops, headways of 5
     s[econds] can be achieved. Theoretically rail systems could operate at headways of perhaps
     60 s[econds] under similar conditions, but such situations are not found in practice”
         Observed bus capacities:
         I-495, New York: 490 / hour;
         Lincoln Tunnel, New York: 735 / hour
         (1994 ITE Highway Capacity Manual, p. 193)

On-line loading: 60 minutes per hour / one bus per 2.4 minutes = 25 buses per hour
Off-line loading: 3600 seconds per hour / one bus per 5 seconds = 720 buses per hour

44,000 seats per hour
720 buses per hour x 61 seats per hybrid bus = 43,920 seats per hour per direction.
Cf light rail at 25 trains per hour x 4 cars per train x 74 seats per car = 7,400 seats per hour per

buses could easily meet transit demand in the DSTT
125 buses per hour x 61 seats per bus = 7625 seats per hour per direction. 125 buses can be
accommodated by the DSTT (see Appendix B, page 2 -- there I used the figure of 63 seats per
bus, but my understanding is that the new, hybrid buses have 61 seats)

25-30 mph
page 4.9-25

Also: table 4.9-17 on page 4.9-48 of the DSEIS states that travel time from downtown to SeaTac
airport with LRT will be 42 minutes, which is stated to be a 14% savings "from existing".
X - 14% = 42min
X = 49 min ("existing")
However the 194 bus makes it from downtown to SeaTac in 29 min at 5 pm, according to its
examine honestly
See footnote 4.

obvious choice for this corridor
Much information about HOT lanes will be gleaned when the SR167 HOT pilot project is put in
place. The BRT/HOT Alternative would build on and extend the 167 project methodology,
having rail-quality off-line bus stops as well as dedicated off and on ramps, neither of which will
be part of the SR167 HOT project.

huge transit capacity
720 buses per hour (see footnote 17) x 61 seats per bus = 43,920 seats per hour per direction

require one bus traveling each direction on the bridge at a time
According to Figure 4.9-10 (page 4.9-26) rail headways on the I-90 span could eventually be as
little as 5 minutes.
60 min per hour / 5min per train = 12 trains per hour
12 trains per hour x 4 cars per train x 72 seats per car = 3456 seats per hour
To equal this, the number of buses required is:
3456 seats per hour / 61 seats per hybrid bus = 57 buses per hour per direction
3600 seconds per hour / 57 buses per hour = 63 seconds per bus
Assuming a HOT lane in free-flow, bus spacing at 60 mph becomes
60 miles per 3600 seconds / 1 bus per 63 seconds = 1.05 miles per bus
1 bus per mile
The length of the floating portion of the I-90 span is about a mile. So for buses to equal the
seated capacity of Link on the bridge, as one bus is driving onto the bridge from Mercer Island
another will be driving off of it towards Seattle. Alternately if one bus headed to the eastside is
in the middle of the bridge, the eastbound portion of the bridge will otherwise be unoccupied by

The existing DSTT cost approximately $600 Million. If we double that cost to $1.2 Billion this is
still a small fraction of the Eastside Link cost (see previous footnote).
A tunnel optimized for buses would have two passing lanes in the stations (instead of one under
the current DSTT), allowing “skip-stops,” with the consequent at-least doubling of through-put.

ultimate development
Others have also called for the pricing of all roads at all times. Because the overwhelming
number of roads are uncongested, this proposal, which I do not support, is primarily a revenue-
raising mechanism meant to replace the gas tax, rather than a congestion-regulation and capacity-
enhancement mechanism.

re:    Draft Environmental Impact Statement
       Regional Transit System Plan, October 1992

Dear Mr. Bush:

I have been, and remain, an advocate of Congestion Pricing. My remarks are directed
first at the Draft Environmental Impact Statement's (DEIS) analysis of this concept and
then to other aspects of the DEIS.

It is stated in section 2.6.9 that Congestion Pricing "could not by itself meet the
objectives of the System Plan". I take the word objectives to mean goals as delineated
beginning on page x of the DEIS, the most important of which is the first, ensure the
ability to move around the region. If this assumption is correct, then the statement of
non-attainment is either false, meaningless, or grossly misleading.

To see that the statement is false or meaningless, ask yourself the following question,
"Will there be enough parking in downtown Seattle in the year 2020?" There certainly
won't be enough free parking to meet the demand, as there isn't today, but there certainly
will be enough parking for those who are willing and able to meet the price. Likewise in
a Demand Management alternative there would, by definition, be the ability to move
around the region for those who are willing and able to meet the price (and for others if
the money thus collected were dedicated to making transit frequent and cheap). The
questions are, what is that price, and how does it compare to the alternatives delineated in
the DEIS, considering all relevant factors such as the cost of congestion, and cross-
subsidation of one form of transportation to another. The DEIS doesn't even attempt to
answer these questions.

To see that the statement is grossly misleading it is only necessary to repeat it with
emphasis changed: Congestion Pricing could not by itself meet the objectives of the
System Plan. But then neither could the other alternatives. None of the alternatives by
themselves will preserve communities and open space, improve the region's
economic vitality, or preserve environmental quality. "Implementing the System Plan
by itself will not solve congestion on the region's freeways" (p. xiv). "No transit
alternative will have much of a land use impact unless other complementary actions are
associated with it." (p. 3-119)

Of all the alternatives by themselves Congestion Pricing (CP) comes the closest to
meeting the four objectives. In theory CP could meet all the mobility needs of the region.
More realistically, it would likely be teamed with Transportation System Management
(TSM) as delineated in the DEIS, since even in a the freely flowing system created by
CP, the region's freeways would most likely continue to have "choke points" where
traffic slows, and it would be good public policy to give high occupancy vehicles (HOVs)
a way around these. If TSM were implemented before CP, then the technology used to
enforce TSM would be in place to implement Congestion Pricing at a later date.

In section 2.6.9 the DEIS also mentions equity, privacy, and land use as issues it indicates
would need looking into.

The equity issue can be addressed in a couple of ways. The first way is to note that if
funds collected in a TSM/Congestion Pricing (TSM/CP) alternative were dedicated to
transit, making it frequent and inexpensive, possibly even free, then the relatively well off
would in fact be paying the transportation tab for the less well off. Contriwise local
sources for the other alternatives, sales tax, motor vehicle excise tax, gasoline tax,
parking tax, are to one degree or another "regressive". The second way is less obvious:
"As paradoxical as it may seem, by raising the cash cost of certain types of trips, virtually
all trips can be made more economically." (Market-Based Solutions to the
Transportation Crisis, Bay-Area Economic Forum, May 1990, p. 12)

I have to assume staff didn't look into privacy issues since 45 minutes investigating it
would have shown that this issue has been met.

Land use issues would indeed need to be investigated since there would be spillover from
priced to non-priced roads. However, the DEIS made no attempt to investigate such
spillover in the alternatives considered. "By 2005, 'normal' congestion will cause about
75 million annual person-hours of delay" (p. 1-4), much of which will obviously spill
over onto secondary streets as it does in Los Angeles today. Since, as I will later discuss,
even the minimal effect the other alternatives are projected to have have on congestion is
highly suspect, spillover is something that should be studied under all alternatives.

Additionally, under TSM/CP demand elasticities would have to analyzed.

Turning to other aspects of the DEIS. The bedrock of the evidently preferred alternative,
Rail/TSM, is that rail is stated to have much greater capacity than the bus alternatives.
Since this greater capacity has been presented here and elsewhere as a fact, I was
surprised to find that not all experts agree with this "fact". Their argument is as follows:
as long as busses have somewhere to go at the other end, a "busway" can carry more
passengers than a railway.

Think of a stretch of road, like the floating bridges, on which there are no stops. Then
consider that busses going, for instance, to Mercer Island can exit there without impeding
the busses following. Likewise busses going to Factoria or Isaquah. This assumes that
there is "elbow room" at the exits for busses to stop, discharge and take on passengers,
and then get back on the freeway. On the other hand in a rail or transitway situation, as
sketched on page xiii, when one vehicle stops, it impedes all following vehicles, thereby
creating the need for adequate "headways", so that they don't run into each other.
On page xvi of the DEIS it is stated that one HOV lane can carry between 4,800 and
5,700 people/hour, a busway up to 9,400 people/hour. A "back of the envelope"
calculation of a bus-only HOV lane (i.e. an HOV lane fully occupied by busses) is as
Bus @ 40 mph, 44 seated people/bus
800 busses/hour x 44 people = 35,200 people / hour,
or nearly four times the number indicated in the DEIS.

Obviously this hangs on the ability of busses to freely exit the freeway, and freely get
back on. In certain cases, most notably downtown Seattle, this may present a question. I
will deal with that question later.

One issue that I didn't see analyzed in the DEIS is that of the flexibility of busses verses
trains. This shows up in the relative ability to change concentrations of service, as well
as in the relatively greater need for transfers in a train system.

One reason the downtown Seattle bus tunnel was built is that it was perceived that people
don't like to transfer. A train system maximizes the number of people who have to
transfer. Since with a train system "feeder busses" can't get on the "main line", people
either have to transfer from bus to train, or a much more extensive parking system has to
be built around the stations, obviating a significant portion of the business concentration
assumed for them, as well as defeating whatever environmental gains were expected in
getting people out of their cars altogether.

Turning to rail. The DEIS repeatedly states that rail has capacity for 22,000 people/hour
for a single rail line. I have been told that BART carries 72 seated people in 10 cars, 3
minute headways, 20 trains an hour, or 14,400 people/hour, about 65% of the projections
in the DEIS. Does the DEIS assume standing people? Will the downtown Seattle transit
tunnel accommodate 10 car trains? Are shorter headways than have been able to be
achieved in the Bay Area assumed? Or is this two lanes of rail?

If the above calculations are even "ballpark" correct, then a bus-dedicated HOV lane (a
"double diamond" lane?) which is unconstrained as to exiting and entering, could carry
something on the order of 2.4 times as many people per hour as a rail system. The
"extra" capacity could obviously be used by vans and carpools.

Now some miscellaneous comments on the DEIS.

It is stated on the same page that "In areas where there is efficient mass transit, business
and residents cluster near transit facilities." Referring to the previously quoted Market-
Based Solutions to the Transportation Crisis (MBS), page 5: "Less than four percent ... of
the workers at offices around Walnut Creek's BART stations use BART to get there."
The DEIS makes no attempt to cost the system on a per person basis. However using the
data on page xxxvi, one can make an attempt. The capital cost of the Rail/TSM
alternative is stated to be $11.5 Billion. The cost of TSM, is $4.7 Billion. Assuming 7%
bonds, the interest on the Rail/TSM alternative is $805 million/year; interest on the TSM
alternative is $329 million/year; the difference being $476 million/year. Likewise
subtracting the operating cost of TSM from rail gives a difference of $93 million/year.
Together this equals $569 million/year, the cost attributable to rail. For this one is
(allegedly) gaining 23.6 million passengers/year. Dividing $569 million by 23.6 million,
the incremental cost/passenger of rail is $24.11. Similar calculations for the TSM
alternative give a figure of $5.41/passenger, about 22% of the cost for rail.


             Riders             Capital Costs              7%              Operating Costs

Rail/TSM        157.3               $ 11,500           $ 805                          $ 492
TSM             133.7                   4,700            329                            399
                 ---                     -----           ----                            ---
                 23.6                 $ 6,800          $ 476                           $ 93


                                                       $ 569

$569/23.6 = $24.11/passenger

Assume a commuter using the system workdays:
$24.11/trip x 2 trips/day x 5 days/week x 50 weeks/year =$12,055 commuter/year.
The equivalent cost per bus commuter year comes to $2,715/year.

This assumes that a Rail/TSM system will capture 18% more passengers than a TSM
system (p. xxxvi). A lot of people don't think this is realistic. Although the Bay Area has
much better demographics and geography as well as a more extensive system than is
proposed in the DEIS, there "transit use has shown an average rate of decline of almost 2
percent per year" (MBS p. 4). To the extent that rail captures fewer riders, the
incremental cost per passenger of Rail/TSM over TSM will be that much greater. If
Rail/TSM captures 9% more riders than TSM, the cost of rail will be $47.03/trip
($23,515/commuter/year); if 5%, $85.05/trip ($42,525/commuter/year). At that point, of
course, it would be cheaper to pay people to stay home.
Added to the costs shown here should be the costs of delay. The data to analyze this
doesn't appear to be in the DEIS. However it is mentioned on page 1-4 that by the year
2005 "'normal' congestion will cause about 75 million annual person-hours of delay."
Presumably this figure will be considerably higher in 2020, say 100 million1. If
Rail/TSM combined with the Commute Trip Reduction Law increases transit ridership by
13% (p. 3-89), assume (crudely) a decrease in delay by that amount:
100 million less 13% = 87 million person hours of delay.
Assume a delay cost of $15/hour (1992 dollars),
87,000,000 hours x $15/hr = $1.3 billion per year.

 So to the $569 million annual cost of the system should be added $1.3 billion in delay
cost, for a total of $1.87 billion per year. The question for TSM/Congestion Pricing is,
can it be implemented for less than this? While I am sure that the answer is yes, the data
to calculate this cost, most notably the "demand elasticity" (at what congestion price level
will people switch to transit) is not in my possession.2 Presumably Metro staff could
derive this information.

As outlined in the DEIS there seem to be two flaws to the bus alternatives (TSM, and
Transitway/TSM). One is the capacity of downtown Seattle streets to take the bus traffic.
The other is the bottleneck that would be created by dedicating the express lanes on I-5 to
a transitway. (The second is considered a "fatal flaw" to the Transitway/TSM alternative
(p. xxxiii); however, on page 2-20 it is stated "like the TSM alternative, [the
Transitway/TSM] would replace the reversible lane on I-90 and I-5 with a two-way
transitway" (emphasis added). So apparently the TSM alternative envisions a transitway
on I-5 north, even though it is nowhere identified as a "fatal flaw".)

As to the capacity of downtown Seattle streets, first of all one wonders if this is a major
problem why wasn't the transit tunnel built with more capacity to begin with? Be that as
it may, there are various possible ways around this problem. They include dedicating one
or more surface streets to "transit only" either during rush-hours or full-time; making
some busses stop only at the north or south tunnel stations and then getting back on I-5
north or south; making some busses stop somewhere else along the HOV (transitway)
running through downtown; using double-articulated busses; building another tunnel
(expensive, but a hell of a lot cheaper than a rail system).

1. Very roughly: Vehicle Miles Traveled (VMT) increased 450% between 1960 and
1990 (Figure 3.14, p. 3-78), and is projected to increase 78% from 1990 to 2020, for an
increase (1960 - 2020) of approximately 800%. 2005 is 45 years from 1960 when we
assume no congestion; year 2020 is 60 years from 1960. Using (undoubtedly inaccurate)
straight line projections, 60/45 x 75 million = 100 million person hours of delay. VMT
won't increase in a straight line function. On the other hand delay probably increases at
an increasing rate. I'm sure Metro staff can come up with better figures.
 . A parking rate of about $6/day apparently causes about one third of people working
downtown to take the bus, which costs $2 - $3/day ($1 - $1.50 each way), or a difference
of $3 to $4/day ($1.50 to $2 each way). Would a congestion fee of $5 each way cause
50% of people to turn to transit? If so by 2020 VMT would drop by 11% from todays
level: 50% of 178% = 89% of today's traffic.
As to the I-5 north bottleneck "fatal flaw", one wonders why 75 million of hours of delay
by 2005 isn't in itself a "fatal flaw". Presumably the bottleneck is "fatal" while the delay
isn't because people will see something being taken away from them with the former (the
"don't-take-candy-away-from-a-baby syndrome"). Some possible ways around this
"baby" include: move the entrances to 520 onto the express lanes north and south (from
NE 50th and downtown), increase single occupancy vehicle (SOV) lanes north by
increasing the Battery Street tunnel lanes to 6 and improving SR 99 capacity to move
traffic, connecting I-5 with SR 99 at the West Seattle Bridge, widening I-5 by one lane
each way from north of the Ship Canal bridge to Northgate, or building a SOV/HOV
tunnel connecting 23rd Avenue East to the University Village area (all expensive, all a lot
cheaper than rail).

The DEIS assumes that improved transit will result in fewer people on the highways
(3.8% less, Table 3.9.3, p. 3-90). However experience calls this assumption into
question. When the new I-90 bridge opened, the "extra capacity" that was supposed to
last 15 years (or whatever it was) lasted about 15 minutes. Everybody wants the other
guy to use transit so he can use his car. London, Paris, and New York are all in gridlock.

This being the case, the argument that any of the alternatives, with the probable exception
of TSM/CP, would do much for air pollution is a pipe dream. Quite simply, given the
existing and projected vehicle fleet mix if you don't get rid of congestion, you don't get
rid of air pollution.

Even if you were to believe the projections of diminished car trips and VMT, the
Regional Transit Project would be a ridiculously expensive way to tackle the problem. It
would be several orders of magnitude cheaper to simply buy up clunkers (which do most
of the polluting) and/or convert a part of the vehicle fleet to compressed natural gas or

A word about technology relative to the TSM or the TSM/CP alternative. The means to
electronically collect tolls is being used in various parts of the country. One problem
with HOV lanes is that there are an awful lot of "cheaters" using them (50% ?). The
technology used to collect tolls could also insure that authorized vehicles use the HOV
lanes. If it were desired, these vehicles could be made to "check in" at freeway onramps
to make sure there were carrying the right number of people, possibly using something
akin to the remote tellers at drive-in banks: the remote "teller" would authorized that
vehicle to be on the HOV lanes for the following hour or until it exited the freeway. This
same technology could be used to charge tolls under a TSM/CP alternative. As stated
earlier the privacy issues on this subject have been met, and staff simply needs to consult
the relevant literature.

My conclusions (other than that the belief in "salvation from steel wheels" should
possibly be considered a cult and referred to the proper authorities) are as follows:

It appears that under the right circumstances TSM can handle as much traffic as rail if not

Busses are obviously much more flexible than trains and can minimize transfers.

The two bottlenecks to a bus (TSM) system, downtown Seattle and the I-5 expresslanes,
don't seem to be insurmountable problems. Certainly they are solvable for much less
than a rail system.
The technology that would be desirable to enforce a bus (TSM) system could be used at a
later date if the region wanted to move to a TSM/CP system.

None of the alternatives examined in the DEIS would have much affect on air pollution.
Congestion Pricing could have a significant affect, but that would need to be studied.

Therefore an alternative that should be further examined is TSM including SOV
improvements, with a possible later addition of Congestion Pricing (TSM/CP).

However, if the Federal Government is willing to pick up 90% of the tab for trains,
kindly ignore the above.

March 19, 2004

Douglas B. MacDonald
Secretary of Transportation
PO Box 47300
Olympia, Washington 98504


Thank you for your letter of February 6, 2004. [1] Having mulled this over through the
kids’ winter break, my annual all-guy ski trip and some elective surgery, I continue to
believe that the central issue here is the statement, made in your letter to Secretary
Mineta, that the National Review Panel (NRP), which was convened to study this
region’s transit choices, concluded that “a new rail corridor was the only practicable
choice for meeting the need to move more people in the I-5 corridor.” There are two
aspects to this statement. The first and less important is, did the NRP say this? The
second and more important is, is it correct?

Concerning the first aspect, given that your letter was written specifically in support of
Sound Transit’s light rail project, and given that the relevant EIS, presumably informed
by the NRP, specifically rejected light rail, I will stand by my previous statement that
your claim was “mis-informed.” [2] However the real issue is not what the NRP did or
didn’t say. The real issue is whether or not rail is the “only practicable choice for
meeting the need to move more people in the I-5 corridor.” It seems clear on its face that
it is not. In fact it seems clear that BRT gives at least an order of magnitude more
“mobility for the buck” than light rail. [3] And considering the bucks we are talking
about (“a billion here, a billion there”), this is no small matter.

The central thrust of your 2/6 letter to me is that the bus capacity I derived for freeway
HOT lanes is heavily constrained by the capacity of the Downtown Seattle Transit
Tunnel (DSTT). I agree with this. But “the dog that didn’t bark” in your letter is any
disagreement with the capacity figures I derived for HOT lanes. I will apply the “silence
equals consent” rule (which phrase I may have made up, given that none of my attorney
friends seem to know the Latin equivalent), to indicate agreement that buses on, for
example I-90 or I-405 HOT lanes, would have far more capacity than rail in those
corridors. I do agree that bus capacity on prospective I-5 HOT lanes is constrained by
the “pinch point” of downtown Seattle [4] (although, again, assuming HOT lane build-
out, it is not similarly constrained in the region’s other freeway corridors).

Taking your figure of a 2-way bus capacity in the DSTT of 125 buses per hour per
direction (which number is likely to be low) [5] and 63 seats per articulated bus, gives
7,875 seats per direction per hour. In order to produce an apples to apples result, I will
not take some fraction of bus seats vs some multiple of rail seats; that would be more
nearly apples to cantaloupes. [6] On the rail side, while it is unlikely to the point of
impossibility that Link could ever achieve 2 minute headways, [7] for sake of this
discussion, I will take your number of 8,880 seats per hour per direction (74 seats per car
x 4 cars per train x 30 trains per hour), an additional 925 seats per hour or about 12%
more than the bus number above. [8] Now, given that in order to achieve the rail number,
Link will have to be completed through to Northgate at a cost of something like $7
Billion [9] the question becomes, it is possible for bus to achieve this capacity for
something less than this figure? [10]

Well, duh. Ignoring for the moment the ways that exist to achieve greater operational
efficiencies, [11] and ignoring all the relatively simple and/or inexpensive remedies that
exist to increase through-put [12] – ignoring all that and just assuming that we built
another bus tunnel once the current one is maxed out some decades hence, that in itself
would double and could triple [13] the capacity you indicated for the current DSTT,
which by your figures is currently 56% utilized. [14]

Adding this up produces something on the order of an eventual bus through-put in excess
of 23,000 seats per hour per direction, [15] well above of any plausible transit demand,
and of course many times the number theoretically achievable by Link. [16] The fact that
this figure is only half the full bus capacity of a freeway HOT lane, [17] just means that
these lanes are never likely to be fully utilized by buses, and will always have excess
capacity for non-bus use. [18] Another way of putting this is that a HOT lane system will
always have a robust transit capacity buffer, and thus will never need to become a bus-
only lanes (busway) as envisioned by the National Review Panel. [19]

The cost of a new DSTT (“DSTT2”)? Well, the existing one, if memory serves me, cost
about $600MM. So double (or triple) that. As for a bus lane on the I-5 reversible lanes,
a WSDOT number for that (Ravenna to Stewart) is $59MM. [20] By any measure, it’s
still a fraction of the Initial Segment cost, let alone Link from SeaTac to Northgate, not to
mention a 150-mile build-out of the system.

The conclusion I take form the above is that while, as you state in your letter, the DSTT
limits bus capacity in the I-5 corridor, given some simple investments, it doesn’t limit it
to the point where bus through-put is less than rail. And given major investment (but far
less than required for a comparable length of light rail) bus can give substantially more
capacity. In sum: for less money, equal capacity / for equal money, more capacity.
Either way: “more mobility for the buck.” If this was not clear at the time of the National
Review Panel, it certainly is clear now. [21]

My only other point concerns the consent of the governed. You said,
       Talking with Aubrey Davis about your letter, he points to the strong voter support for the
       transportation program containing light rail in the 1996 Sound Move vote, especially in
       the North King Subarea where the tax burden falls to pay for light rail. Even as the plan
       has been shaped (and unceasingly attacked) [22] in intervening years, voters in the area
       continue to favor it as recently shown by their tally against Initiative 776. Transportation
       policy must be rooted in popular support as well as in technical analysis; Link Light Rail,
       despite the controversy it attracts, seems to stand with a strong measure of both.

There are a number of things to note here. The first is that we the voters were lied to
before the 1996 vote. Sound Transit said that building the light rail system would be the
equivalent of adding a 12 (sometimes 16) lane freeway. In fact not a few ST board
members, perhaps in a kind of “blow back,” appear to believe that to this day. [23]
Obviously if you added a 12 lane freeway, you would be taking a big whack out of
congestion. [24] Unfortunately the Link system would have no noticeable congestion
effect. [25] As for the 776 vote, before the vote we were repeatedly told by Sound
Transit supporters that it had nothing to do with light rail. After the vote, it was a
referendum on it. [26]

As a summary I could do worse than quoting Emory Bundy, in the title of an essay he
wrote before the ’96 vote: “If the [Sound Transit light rail] project [were] defensible, it
could be defended by telling the truth.” Unfortunately it isn’t, so it isn’t. Yes, if we had
tens of billions of dollars burning a hole in our collective pockets, I suppose it would be
nice to have a rail system (although in that case it should be the kind of grade-separated
system envisioned by the National Review Panel). But I haven’t noticed that we are
suffering from such an embarrassment of riches. Since I am the author of the phrase
“WPPSS on Wheels,” I will end by saying that, in my view, this is pretty much what the
Link light rail project amounts to. I realize that you have a different view.

       "We wish we had never started the whole thing. Fixed rail is not the answer to
       the transportation needs of our city. We should stop all this insanity that has
       gone on these past years."
       Richard Riordan, Mayor of Los Angeles and Chair of the Los Angeles County
       Metropolitan Transportation Authority, on public radio program, Which Way LA?,
       June, 1998.


Donald F Padelford
As a postscript let me say something you already know, namely that I am fully on-board
with the WSDOT in getting a HOT network established. We may have failed in this
legislative session, but I am reassured by the words of Winton Churchill: “The
Americans can always be counted on to do the right thing – after exhausting every other
alternative.” I would say the other alternatives are just about exhausted.

Also, if you would like to get a few people together for lunch, I would suggest (if they
will consent) Emory Bundy and Chuck Collins for my, in your word, “seconds.” I trust,
however, this doesn’t entail, as the term might suggest, a duel.
Entries in this arial font are notes to myself that were added after letter was sent.


This was a response to my email to you of 10/4/03 with clarifying emails sent on 10/25/03 and
10/27/03; which email communication, in its turn was a response to your 7/3/03 letter to
Secretary Mineta, written in support of the now-approved FFGA for Initial Segment of Sound
Transit’s Link light rail project.

I think that this is adequately covered in previous communications, but to briefly recap: The 3/93
EIS rejected “light” rail, as well as busways, and supported “heavy” rail. I think it’s a fair
inference that what the EIS was rejecting in “light” rail is lack of grade-separation. Thus the EIS
(informed by the NRP) rejected non-grade-separated rail transit. It seems likely, and is in
conformance to my memory of the then-discussion, that over-head-feed (ie “light”) rail that is
grade-separated in it core would have passed muster. However the EIS examined at least two
iterations of “real” (non-grade-separated) light rail, such as Sound Transit is now beginning to
construct, and explicitly rejected that modality. Bus rapid transit running on HOT lanes (BRT on
HOT) was not on the radar screen at that time and was thus not considered. It is also a fact that
neither the ’93 EIS nor any other EIS or similar analysis compared specifically Light rail to Bus
Rapid Transit. Repeat: LRT has never been directly compared to BRT. Never happened.

As communicated earlier I believe that the reason we have “real” (non grade-separated) light rail
running down MLK is that the Seattle City Council, during the mayoralty of Norm Rice, “played
the race card” to divert the system, which was to run elevated (like Vancouver’s Skytrain) down
the Duwamish, to the Rainier Valley, where, due to some suspect budget constraints, it became an
at-grade system. The irony of this, of course, is that, thanks to the race card, the predominantly
minority residents of the valley get a dangerous at-grade system while the white, middle-class
residents of the north end get tunnels. Besides being dangerous, such an at-grade system is also
slow, low-capacity, and puts a monkey wrench in way of east-west travel. In a pattern that has
been repeated numerous times, the analysis that was produced to support the MLK route was in
essence fraudulent.

If Link had gone where and how objective analysis at the time said it should go (elevated down
the Duwamish) it is likely that the opposition that has formed around this project would never
have coalesced, and that the monorail movement, which has as its mantra that monorails “don’t
get stuck in traffic,” would never have been born. Thus the reason that Link has, in your words,
been “unceasingly attacked” is a direct result of disingenuousness in the process that gave it birth.

Of course there are lot of unknowns, and any cost comparisons are somewhat “back of the
envelope.” For one thing Sound Transit doesn’t know (or says it doesn’t) how much the
extension to SeaTac and Northgate will cost (which doesn’t stop Ron Sims from being
“confident” that it can be built within existing taxing recourses -- now wait a minute, if your don’t
know how much it will cost, how can you …. oh, never mind). None the less our best guess (via
the good offices of Jim MacIsaac) for the SeaTac to Northgate line is in the $7B range. If a full
system is 150 miles, and if the rest costs about the same per mile, this would produce a system
cost of about $50B. As for BRT on HOT, the main thing that needs to be done is to finish the
HOV lane system, which according to the WSDOT would cost on the order of $1.65B for the
“core” system (not including the cost of ramps and connectors to make it seamless), and then
convert the HOV lanes to HOT, which can be financed from HOT revenues. While special ramps
and connectors are not needed right away, a WSDOT number for that is approximately $290MM.
Thus finishing the core HOV system and building the HOV connections should cost on the order
of $1.9B, about 1/26th of the “back of the envelope” cost for Link above. Given HOT conversion
(to keep the lanes in free-flow in perpetuity), for this you would be getting a BRT system running
150 miles and covering the entire metropolitan Puget Sound region at 60 mph 24/7. Even if the
relative cost figures are off by a factor of 100%, this still is an order of magnitude difference
between the two.

There two, off-setting, errors above: Link SeaTac to Northgate is about 24 miles, not the 21
miles used in the letter. However, this is off-set by updated cost data: the SeaTac to Northgate
cost, according to new (to me) information from MacIsaac (email from JM 4/24/04) is $7.9B vs the
reported $7B
$7.9B / 24 miles = $329MM / mile; $329 x 150 miles = $49.5B, essentially equal to the $50B
figure mentioned in the letter.
Also the above figures do not include the cost of a southbound bus lane on I-5 at about $59 MM.
Thus the total cost for a BRT roadbed would be approximately $1,650 + 290 + 59 = $1,999MM
1,999 / 49,500 = 1/25, not 1/26 whatever

While not all I-5 buses stop in downtown Seattle (eg airporters from Skagit do not), almost all do;
it seems like a reasonable simplifying assumption to assume they all do.

Previous Metro analyses prior to 8/01 (see footnote #8) showed a capacity of 150 buses per hour
per direction. Our understanding of the 125 figure is that Metro was instructed to assume no
operational changes or new efficiencies (I believe there is documentation to this point). Having
said this, my knowledge of the nuts and bolts of bus operations is very limited. If you want to get
the real scoop on achievable bus efficiencies you need to talk to someone who is both
knowledgeable and is an honest advocate for that technology. In this region you couldn’t do
better than Chuck Collins, the former head of Metro.

Either you have to compare theoretical capacity to theoretical capacity, or achievable capacity to
achievable capacity. It just isn’t kosher to compare the theoretical capacity of rail to the
achievable capacity of bus. However, I’m afraid that this is exactly what your letter does. In my
case I am using a form or theoretical capacity, seated capacity in each case, which is apples to
apples. I leave achievable capacities in each case (oranges to oranges) to those with more
expertise than myself.

However, the concept that if you put a bus on rails, passenger capacity goes from 80% of the
number of seats to 185% is sort of ridiculous.
If, as you aver, this is partially a function of the “shorter trips” for light rail, that just shows that
what Sound Transit is building is not a transit “spine” but a gold-plated local bus line substitute
(instead of a bus line down MLK, we in effect get an extension of the Waterfront Trolley down that
     BART is of course a completely grade-separated system. It is my understanding that the best it
     has been able to achieve, after decades and billions and billions of dollars, is slightly better than
     3 minute headways. In order to get 2 minute headways for Link, the concept that I have read is
     that a train would come from the south, then one from the east on I-90, then one from the south,
     etc. The south and east trains would be on 4 minute headways, and combining them would
     produce 2 minute headways going north from downtown. But can trains running at-grade
     through the Rainier Valley really reliably maintain 4 minute headways, and merge, with the
     precision of a Swiss watch, with trains from the east? Of course not. And what would a train
     every 4 minutes do to cross traffic in the valley? Devastate it. (From the 1993 EIS, page 2-50:
     Non-grade-separated “[t]rain frequency is also limited, since there must be time to clear
     intersections between trains. Conventional transit practice and highway standards suggest that
     when train frequencies are under 6 minutes, cross traffic on arterials will be affected to the extent
     that grade separation is necessary.”) So the concept that Link will run on 2 minute headways
     north of downtown under such a scenario is not credible (if the grade-separated BART can’t do it
     …). If Link were to eventually achieve 6 minute headways with both feeder lines (south and
     east), that could produce 3 minute headways north of downtown, which, as I understand it, is the
     figure that Sound Transit originally posited before it figured out that 6 car trains won’t fit into the
     DSTT stations (see below).

     The 1996 Sound Move document envisioned 6 car trains. When it was pointed out that 60 foot
     rail cars haven’t been manufactured since WWII, the six 60’ railcars morphed into four 90’ cars
     (the stations are 380’ long). But interestingly the 60’ and 90’ foot cars each were to carry about
     the same number of people (125 vs 137), so while the length of the cars increased 50%, the
     number of passengers increased a mere 10%. Didn’t someone bother to measure the stations
     before asking the taxpayers for billions? Or were they perhaps contemplating double-decker rail
     cars in Sound Move? Anyway, this little fiasco required Sound Transit to decrease the headways
     in order to maintain (theoretical) capacity. This was accomplished as follows: 6 cars trains
     running every 3 minutes produces 120 cars per hour (20trains/hr x 6cars/train = 120cars/hr) This
     was changed to 30trains/hr x 4cars/train = 120cars/hr. The only problem is that there never was
     any realistic prospect of running trains every 2 minutes.

My understanding is that the 8/21/01 “Evaluation of Joint Operations in the DSTT,” referenced in
your letter, is, to put it charitably, a flawed document. Metro at this point has become essentially a
captive agency of Sound Transit. Therefore work product that comes from Metro should be
examined with a jaundiced eye. People working there know the score. Transportation professionals
in other agencies who showed insufficiently-attuned political instincts were shown the door.

     With apologies to Shakespeare, the dialogue between Sound Transit and Metro may have gone
     something like the following:
     Sound Transit: Do you see yonder cloud that's almost in shape of a camel?
     Metro: By the mass, and 'tis like a camel, indeed.
     ST: Methinks it is like a weasel.
     M: It is backed like a weasel.
     ST: Or like a whale?
     M: Very like a whale.
   See footnote # 3

   Alternately, if you threw $7 Billion at a bus system, could you do more?

   As stated earlier, I am certainly no expert in this realm, but I am given to understand that if one
   were to use the tunnel only for outbound and “inter-lined” runs (ie runs that start north of the
   downtown and, sometimes with a change of number, continue on south of downtown, or visa
   versa, as opposed to runs that terminate in downtown), that efficiency would be improved. I am
   further given to understand that currently even dead-headed buses use the DSTT. I believe that I
   am only scratching the surface here.

These would include, from mundane to perhaps fanciful:
    Using 3rd Avenue as a bus mall, either during rush hours of full-time
    Platooning buses
    Using double-articulated buses
    Creating bus-trains in controlled-access situations like the DSTT by electronically connecting
           buses as has recently been demonstrated in Japan.
    Intercepting some buses north or south of downtown and transferring passengers to a shuttle
           (monorail, personal rapid transit, moving sidewalks, gondolas, bike/Segway lanes, etc)
    Narrowing lanes (with the implementation of self-guidance technology in the tunnel) and
           narrowing sidewalks to produce two passing lanes in the stations, thus allowing “skip
           stops,” with the consequent doubling of through-put from the maximum now envisioned
           for the DSTT.
    Punching out station walls into adjoining properties to get an additional passing lane as above.

   ie if we had two passing lanes in the stations as opposed to the existing one passing lane, it would
   be possible to implement skip stops, thus doubling the capacity of the new tunnel when and if
   needed. Thus, using your figures, the through-put could be 125 (the current DSTT) + 2 x 125 (a
   new DSTT) = 375 buses per hour per direction.

   (Using the normally accepted figure of 150 buses per direction per hour for the DSTT, the
   eventual through-put could be 450 pdph.)

   Thus from today’s through-put, capacity could be increased by a factor of
   375 / (125 x 56%) = 5.4 or 540%. That should do it!

   375 buses per hour per direction x 63 seats per bus = 23,625 seated passengers per hour per

   According an email from Jerry Schneider 2/25/04 Bogota and San Paulo BRT systems carry
   30,000 pphpd.
Calculated above at 8,800 seats per hour per direction, assuming (unrealistic) 2 minute headways.
Therefore, I don’t agree with your statement that “We do know at least one virtual certainty.
Within a short horizon – say twenty years of so into the future – such a [bus] system would not
the capacity to serve the needs in our most congested, highest demand corridors.”
Bus/rail seats = 23,625/8,800 = 2.7 times.

Assuming more realistic through-put numbers for bus and rail of 450 (two tunnels) and
20 (3 minute headways) respectively, the numbers become:
Rail: 20 trains per hour x 4 cars per train x 74 seats per car = 5,920 seats per hour
Bus: 450 buses per hour x 63 seats per bus = 28,350
Bus / Rail seats = 28,350 / 5,920 = 4.8 times

HOT lane:
3600 seconds per hour x 1 bus per 5 seconds x 63 seats per bus = 45,360
Two tunnels:
375 buses per hours x 63 seats per bus = 23,625

Vanpools, qualifying carpools, emergency vehicles, paying non-carpools.

As communicated in my 10/4/03 email, it appears to me that the NRP envisioned a busway with
“on-line” loading/unloading, thus severely constraining its through-put.

As I envision it, a HOT lane build-out would eventually include the now-reversible lanes on I-5
(and I-90). One concept would have a 2x2 HOT format (ie 2 HOT lanes in each direction) south
of SR520 and a 1x1 HOT format north of 520. In this concept there would be a HOT to HOT
interchange at the intersection of I-5 and SR520. Obviously something of this magnitude would
cost in the hundreds of millions of dollars. The above-referenced Ravenna to Stewart contra-flow
bus lane on I-5could be thought of as an interim solution. I would add that this is one of the
benefits of a BRT approach, it allows interim solutions. You don’t have to build out the whole
system at once since buses can, for example use HOV lanes before they become HOT lanes (or
use GP lanes). Thus we could have a pretty good 150 mile system quickly and a superb system
over time. In contrast light rail in this region obviously cannot run anywhere new right of way
isn’t built. The existence of an existing right of way is why the San Diego light rail system was
built at such a bargain price. Likewise with St. Louis and commuter rail in Chicago. If we had
kept the Interurban ROW, this might have been true of this region as well, but of course, we
One, somewhat esoteric point about HOT lanes, is prompted by footnote #1 in your letter to me.
You say that HOT lane “would certainly limit the number of cars that the lane would
simultaneously accommodate.” This subject has been discussed extensively within the HOT lane
community. I think it’s a fair characterization to say that we have concluded the opposite – that
by avoiding the “backward bending” portion of the flow vs density curve, pricing can maximize
through-put. It works much the same way as ramp metering, which increases flow on the
freeways, only more so. -- Also I don’t see why HOT lanes would need to annex any GP lanes
as you state, other than the reversible lanes. And by simultaneously changing, for example, the
Mercer Street entrance to the right-most lane, it may be that no GP flow need be taken away. In
any event it is always possible to add GP capacity unless a “pincer movement” against adding or
subtracting I-5 capacity is undertaken (see footnote #2 in my 10/4/03 email to you).

Also, while it is certainly desirable to have some kind of separation of HOT (or for that matter
HOV) and general purpose lanes a la the SR167 prototype, it isn’t absolutely necessary. After all
our HOV lanes operate without them today.

Note that it’s not even clear that 3 minute headways (20 trains per hour) are achievable. But if it
is, then the rail seated capacity number is 74 seats per car x 4 cars per train x 20 trains per hour =
5,920 seats per hour, considerably less than bus. So if rail headways of 3 minutes are the best
achievable, then bus has more seated capacity today without any further investment, than rail
would have after the expenditure of funds necessary to get from SeaTac to Northgate
(approximately $7B, see footnote #3).

See footnote #2

I got into somewhat lengthy discussion with Greg Nickels on this very subject before he was
elected mayor. He was convinced at the time that it was the gospel truth. (As chair of the finance
committee, he also assured me that he bird-dogged the cost figures very closely and that they
were absolutely solid – this was before the initial billion dollar cost-overrun – haven’t heard from
him on this recently.)
 the ’96 election:
- What was promised by ST was what polls said people would go for, not what analysis said was
- Gerrymandering (per Dan Norton)

In the recent SEIS for the north section of Link this egregious piece of mis-information has again
made an appearance. Obviously the people who put together that document know better. At long
last, have they no shame?
From the 1999 Central Link FEIS, page 3-5: “Therefore, based upon traffic forecasts, the light
rail system will not result in a significant difference in regional traffic volumes … Peak hour
volumes for the No-build and light rail alternatives are also expected to be similar [almost
identical] across all screenlines.” In other words, it won’t do diddley for traffic congestion.

The cute circumlocution that Link would provide congestion relief “for those who use it” isn’t
even true. Trundling down MLK on light rail would be no faster “for those who use it” than
doing so in a bus or car.

Also Rob McKenna, the Seattle Times editorial department, and many others opposed 776 and
currently oppose Link. Obviously for them 776 was not a referendum on Link.

Some Observations on the Updated LRT Master Plan

       LRT from S.200th to Northgate is included in the No Action Alt.
       The updated Long-Range Plan Alt includes the 125 miles of LRT from the 1996 LRT
        Master Plan as follows:
         Phase I from S.200th to Northgate - 25 miles
         S.200th to Tacoma Dome - 17 miles (South King and Pierce subareas)
         Northgate to Everett - 23 miles
         Seattle-Bellevue-Redmond via I-90 - 19 miles
         So.Bellevue to Issaquah - 9 miles
         SeaTac to So.Bellevue (via I-405/BNSF) - 13 miles
         Bellevue to Lynnwood (via I-405/BNSF) - 19 miles
       MacIsaac Estimated YOE capital costs for 125-mile LRT system:
         Link IS - $2.44 billion (current ST estimate)
         Balance Link Phase I - $3.6 billion (based upon ST disclosures; unfunded)
         Balance of 125-mile system - $21.7 billion (If all completed by 2020)
         Unfunded capital balance - $25.3 billion
       The following additional LRT Options have been identified:
         U-District to Overlake via SR-520 (North and East subareas)
         U-District to Ballard (North subarea)
         Northgate to UW Bothell via SR-522 (North and East subareas)
         LRT loop to Paine Field/Boeing via SR-525 and SR-526 (Snoh subarea)
         Westlake Station to S.Lake Union (North subarea)
         SeaTac to Burien extension via SR-518 (South subarea)
         Extension of Tacoma Link from CBD to northwest Tacoma (Pierce subarea)
       Potential Commuter Rail extension options:
         Lakewood to Dupont (Pierce subarea)
         Tacoma Dome to Fredrickson (Pierce subarea)
         Sumner to Orting (Pierce subarea)
       New (Sound Transit?) Streetcar Line of Business (North subarea?):
         Westlake to U-District via 9th Ave/Fairview/Eastlake/Univ Bridge
         Eastward extension of Waterfront Streetcar to 23rd Avenue S.
         Northward extension of Waterfront Streetcar to Magnolia Bridge

Traffic Impacts of 2030 L-R Plan vs No Action

Vehicle Trips - No Action vs L-R Plan impact (Table 4.9-6 of DSEIS):
Corridor 2000-30 Growth               Plan
                Total Per Yr Reduction
North            34%     +1.0%        -1.2%
South            39%     +1.1%        -0.5%
East             48%     +1.3%        -0.8%
Sea CBD         -12%                  -3.2%
Total capital costs of all transit modes with the Action Plan vs No Action are likely in the order of
$30 billion. Add to that an increase of about $10 billion in added O&M costs thru 2030. Is that
$40 billion cost warranted to accommodate less than one year of travel growth over that 30-year

Traffic reductions in the three ex-urban corridors border on the
insignificant. Traffic reduction for Seattle CBD trips is significant,
but the Seattle CBD trips are only 6% of the total trips represented in
the table above. Other than downtown Seattle-centric corridors, the L-
R transit plan has minimal effect on the region's traffic congestion

Transit Impacts of 2030 L-R Plan vs No Action

Table 4.9-9 of the DSEIS shows the following transit ride estimates
compared to total person trips derived from Table 4.9-6:

Alternative           Transit        Total          Transit
                       Trips         Trips          % Share
Existing              286,700      11,000,000        2.6%
2030 No Action        634,500      15,628,000        4.1%
2030 Plan Alt         722,100      15,628,000        4.6%

Note that 80% of the increase in transit ridership between 2000 and
2030 is achieved by the No Action Alternative. The (undisclosed by ST)
$40 billion expense for the Proposed long-range Action Plan achieves
only a 14% increase in new transit rides compared to No Action.

Preliminary Conclusions

A relatively minor capital cost investment in express bus transit over
the No Action Alternative would likely achieve the 15% increase in
transit ridership compared to the Sound Transit proposed LRT-dominated
high-capital cost long-range transit plan. The "free-fare" element of
the former "Chuck Collins" plan alone would likely achieve a greater
rider increase than the ST proposed long-range plan, as would just a
moderate increase in focus on vanpool programs. An increase of only
0.02 in average vehicle occupancy would achieve the same level of new
non-driving patronage as would the $40 billion Sound Transit HCT plan.

huge waste of capacity
Since this BRT-on-busway option, in order to equal the seated capacity of
LRT on the center span, has only *one* bus traveling on the bridge each
way at a a time, it follows that LRT on the center span (with the same
seated capacity) is also a "huge waste of capacity."

page 6,
In reviewing earlier communications, I have been reminded of an email
from staff of Mayor Marshall that
The expectation is that new 'hybrid' alternatives will emerge that reflect the best
pieces of the initial assessment and other new ideas. These 'hybrids' may include
system management techniques such as HOT lanes, new alignments, or other
ie as opposed to formal, third BRT/HOT Alternative.

In that regard I append an email exchange between Mr. Matsuoka of
Sound Transit and myself:

Dear Mr. Matsuoka
Thank you for your reply.

I am of course aware of the SR167 HOT pilot project. Given the success of HOT
lanes in other jurisdictions, I don't think there's any serious doubt that they will
work in this region as well. I have generally followed the Trans-Lake work, but
not in any detail. It is my impression that they are looking at pricing largely as a
financing, as opposed to a flow-control, measure. As you can see from my
communication with Mayor Marshall, it is this latter measure which is of primary
concern to me.

I take it as almost unexceptionable that BRT on HOT lanes would provide far
more transit capacity than light rail in I-90 corridor. The math showing this
(below) is grade-school simple. BRT on HOV (as opposed to HOT) lanes,
however, is a markedly inferior service, since either HOV lanes tend to bog down
(eg at HOV2) at which point their ability to move people deteriorates, or they
appear nearly empty (eg at HOV3 or above) and thus are not carrying anywhere
near their maximum load. Thus HOV lanes can ensure neither maximum flow
nor a guaranteed level of service (LOS). Given this, saying that BRT on HOT
might ("conceivably") be looked at if (and -- I take it -- only if) BRT on HOV is
first chosen as the preferred cross-lake transit option, is rather bizarre. A cynic
might even say that "stacking the deck" in such a sequence would be making sure
that the superior bus alternative is never considered at all.

To reiterate a couple points made to Mayor Marshall, using HOT lanes on the I-
90 center span would ensure that the capacity of the bridge is fully utilized, and
that transit, emergency and other vehicles in these special lanes would move at
60 mph (or whatever LOS is chosen) even at the height of rush hours.

I realize that there are people on transportation boards in this region who don't
understand how HOT lanes (with BRT running on them) work. These people
tend to say that if you've got pricing, you've got to have rail because, otherwise
where will the people priced off the lanes go? Which just shows they don't
understand pricing (ie because pricing maximizes through-put and provides a
congestion-free roadbed for BRT). If professional staff don't understand this,
however, it is because they aren't paying attention to the many places HOT lanes
are in operation today.

It is the responsibility of Sound Transit, the PSRC and WSDOT to see that our
transportation dollars are spent wisely. Deliberately not considering what is likely
 the best use of these dollars in the I-90 corridor is, in my opinion, a
clear dereliction of this responsibility.

I expect better.

      HOT lane issues are currently under the leadership of WSDOT. That
      agency has reviewed a number of possible freeway corridors for
      application of HOT technology, and has chosen SR 167 as the corridor in
      which to do a demonstration project.

      As far as cross-lake, the pricing issue was looked at in the Trans-Lake
      work a few years back. It is my understanding that tolling was not
      embraced on the I90 corridor, but the notion of tolling is still an option
      under consideration for the 520 corridor.

      Looking to the future, our recently-reported study of cross-lake HCT is not
      considering HOT lanes or tolling. I suppose that if WSDOT's HOT demo
      project on 167 proves successful, that conceivably the idea might be
      applied to the cross-lake corridor, particularly if the region chooses the
      HOV/BRT option.

For the reasons articulated above (as well as in my 1/25/05 comments)
studying the BRT/HOT Alternative as a "hybrid" with various other "add-

traffic pipes
Below is the well-known speed vs through-put curve, with speed on the
vertical axis and through-put on the horizontal. As more and more
vehicles are added to a freeway one moves from point 1 to 2 to 3, etc. At
points 1, 2 and 3 speed is decreasing but through-put is increasing.
However at points 5 and 6 both speed and through-put are decreasing.
This is what is known by traffic engineers as "hyper-congestion" and in the
popular parlance as "gridlock." Pricing can keep traffic at point M

thru Bellevue and inflating the result to YOE$ for completion by 2015, increases the cost of East
Link to $3.3 billion plus reserves and financing costs. But no way will Bellevue tolerate surface
alignment and associated ROW impacts along its most major arterial streets. So it must be grade
separated which will likely add another $billion or two. So East Link will cost at least $5 billion
including reserves and finance costs thru 2016.

Addendum Two

page 3, bullet item 4
traditional, outside-in commuting
Note that traditional, outside-in commuting to downtown Seattle represents only
ten percent of region's work trips, and should be weighed commensurately
relative to the bulk of work trips better served by rubber-tired transit.
